Knightsbridge BTEVEM Description
The Knightsbridge BTEVEM BT Evo White Emergency LED Bulkhead is a versatile and reliable lighting solution designed for indoor and outdoor installations requiring maintained illumination and emergency backup. Featuring selectable wattage (9W–14W) and 3CCT colour temperature selection, this adaptable bulkhead allows installers to tailor both brightness and light tone to suit the application.
Delivering between 930 and 1750 lumens in standard operation, the BT Evo Emergency bulkhead is ideal for communal areas, stairwells, corridors, entrances and external walkways. In the event of a power failure, the integrated emergency module provides backup illumination to support safe egress in accordance with emergency lighting requirements (typically 3-hour duration, subject to specification).
With a durable IP65 rating, the BTEVEM is protected against dust and water jets, making it suitable for exposed outdoor conditions as well as damp indoor spaces. The clean white finish and robust opal diffuser ensure smooth, glare-reduced light distribution across residential, commercial and light industrial environments.
